While calling around for estimates Max from LINLI was kind enough to Google my address & gave me the best quote. It seems that LINLI & WT Heating work together. I requested an in home assessment & the recommendation was adjusted upward based upon my future needs. Their price was still MUCH better than anyone else I called. I decided to use them & I am thrilled!!!! Two men arrived & went right to work! They answered all my questions & placed each unit where I wanted them. They also cleaned up & carried away the debris. They demonstrated how to use the units & how to clean the filters. We've had our system now for 3 months. I could not be more pleased. I highly recommend LINLI/WT Heating for a ductless installation!

FYI, I also found their company on Google under Friendship Refrigeration. They are HONEST, very hard-working, courteous and quick! I had dealt with dozens of companies who charge just over $200 to just come and look at your unit. Many even refused to come. Some even told me I had to replace my unit when I have a perfectly functioning unit! Albert and his colleague ( with 30 yrs of AC/refrigeration experience)came this Saturday afternoon walked me thru the whole process and even guaranteed the work as best as they could. I watched him work on the motor and fix it within an hour. They were lovely! I have 3 units and will definitely be calling them again for all my maintenance and needs!

Terrible customer service, expensive and my heater is still broken…read more I spent a lot to have my heater fixed by Interstate (serviceman divulged the company marks up the cost of parts by 300%) and it broke again within warranty. I took the day off of work for an appointment to have it fixed and they never showed. I called their office 3xs asking when the serviceman would show up and they repeatedly assured me he would but couldn't commit to a time. The day passed with no call and no technician. Now the warranty has expired - how convenient for Interstate. The owner called to apologize, but I'm still sitting in the cold with a broken heater. BEWARE!!

I sent him photographs of my old boiler that was in very bad conditions, he recommended replacing it as other companies did and gave us an estimate. His price was the most competitive so we decided to hire them. After replacing the new boiler I had to call National Grid to come and turn our gas back on which was only possible a few days later. Adrian came by again after to verify everything and making sure all radiators were working properly! After dealing with not so honest plumbers in the past and having to be without heat from almost 3 weeks, we are so glad we found ProCore. Definitely recommend it.

When my Mitsubishi central air conditioning system in my Manhattan apartment (Chelsea) abruptly stopped working in the middle of a heat wave the night before the July 4th holiday I was worried I would wait days (even weeks) to find a qualified repair. I called six different NYC HVAC repair companies and either couldn't reach anyone or was told that their first appointment was two weeks away. When I called ProCore (on the recommendation of a friend) I was immediately connected to a technician who listened to the situation and told me he would be there the next morning "first thing". At 8:30am two technicians arrived and immediately got to work. They solved the problem, fixed the system, and even made some minor adjustments to make my system more energy efficient. They were friendly, courteous, professional and obviously very good at their job. Their price was very reasonable - to the point where I gave both of them a little extra to thank them for their excellent work and for coming on a holiday early morning. My apartment immediately started cooling down and the system is working better than ever. Just to illustrate the professionalism: both technicians put "covers" on their shoes that they brought with them so they didn't bring any dirt on to my floor (without even being asked to do that). This is a FIVE STAR business and I will highly recommend them to anyone who needs excellent HVAC / Air Conditioning services in NYC. In a city where there are many options - ProCore is the best of the best and I highly recommend them.

Let me tell you, Tony is a very considerate guy as far as pricing, very knowledgeable in his craft and a very swell guy. In two hours these units were installed and operating as they should. His follow-up calls making sure I was happy with the units were the icing on the cake. I recommend these guys 100%. It is always nice to deal with true gentlemen. Eddy Pena

My central air stopped working at 3am this morning and like everyone else I said to myself, "Oh no, not in the middle of July"! I called All Phase at 8am and they dispatched a tech to my home within 6 hours which given the workload that all HVAC contractors have this time of year was very quick service. The tech arrived early, diagnosed the problem within 15 minutes and dove right into the repair and within less than 2 hours the problem was diagnosed, fixed correctly and the tech himself was very polite and made sure the work area was completely clean and left no debris, an excellent piece of work. Quite honestly even if another contractor offered to do it for free I'd still rather have All Phase Heating and Cooling do the work. There work is simply excellent and they stand behind there work and their prices are reasonable given what their competitors charge. As a matter of fact when they installed my central air conditioning unit their price was about $2,000 less than the big name HVAC contractors that everyone is familiar with due to their large amount of money they spend on advertising. All Phase is by far a much better choice given how expensive HAVC work can be. Try them you won't be disappointed. That's the truth!
